This paper introduces the motion principle of virtual hinge mechanism. According to the characteristics of virtual hinge mechanism, two typical solution of lift mechanism are approved,including the analysis of motion principles,the method of locking door in uplift position,etc. This paper gives a lifting-opening linkage mechanism and analyzes the advantages of the mechanism. The mechanism could provide a reference to design of semi-plug door lift and open mechanism.
